As 2D metamaterials, metasurfaces are well known due to the distinctive manipulation of the amplitude, phase, polarization, and propagation for electromagnetic (EM) waves. However, the existing metasurfaces are mainly designed to control the incident waves. Herein, a coding-feeding metasurface (CFMS) with two functions of dual-band emission and diffusion for incidences simultaneously is proposed. The zigzag emission patch and two arc-split triangle patches for polarization conversion are nested together on a shared aperture of a unit cell for CFMS. The genetic optimization algorithm is introduced for diffusion. A prototype is fabricated and measured to validate the proposed CFMS with dual-function. The experimental results agree well with the simulated data, which verify the diffusion and emission for CFMS. The CFMS with the lightweight, compact, and low profile has the potential applications in imaging, detection, and wireless communication systems for stealth aircraft.

用于扩散和双波段发射的编码馈送超表面

作为二维超材料，超表面由于对电磁 (EM) 波的幅度、相位、极化和传播的独特操纵而广为人知。然而，现有的超表面主要用于控制入射波。在此，提出了一种同时具有双波段发射和入射扩散两种功能的编码馈电超表面（CFMS）。用于偏振转换的锯齿形发射贴片和两个弧裂三角形贴片嵌套在用于 CFMS 的晶胞的共享孔径上。引入遗传优化算法进行扩散。制作并测量了一个原型，以验证所提出的具有双重功能的 CFMS。实验结果与模拟数据吻合较好，验证了CFMS的扩散和发射。CFMS 具有轻巧、紧凑、
